When replacing the rear caliper with opposing 2-piston calipers (φ32, φ34) from GALE SPEED, Brembo, etc., depending on the ratio, the brake pedal stroke may decrease, making it difficult to control. Gale Speed rear master cylinders are designed with a piston diameter of φ12 to match the leverage ratio of common racing steps. This achieves a delicate and controllable rear brake system. ■ Specifications Type: Mounting pitch 45mm \/ Rod end M8 Color: Brown Piston size: φ12 Compatible caliper: Piston diameter φ32\/φ34 opposing 2-piston Bolt pitch: P1.00 Fluid tank: Separate type Fluid nipple (included): φ6\/φ7.3 (90°) Return spring (included): Standard\/Hard ■ Notes * The image is for illustration purposes only.
